linSmith tutorial: First component

As usual, there are several options available to adapt this load. Let's do it with discrete components. Using a capacitor, we can advance to the gray (g=1) circle. Then, we can connect another capacitor in parallel, and obtain a match. Let's try a 40 pF value (just a rule of thumb: about 20 times the wavelength in meters), and see what happens.
Not entirely bad... We moved too far (X too large), so we have to use more capacitance. Using the scrollbar it's easy to bring the capacitor to a value where the endpoint resides just on the Y=1 circle. Click on Update to transfer the new value to the component list. (about 77 pF).
